Isaiah 17:11

17:11 The day you begin cultivating, you do what you can to make it grow;

the morning you begin planting, you do what you can to make it sprout.

Yet the harvest will disappear in the day of disease

and incurable pain.

Isaiah 58:2

58:2 They seek me day after day;

they want to know my requirements,

like a nation that does what is right

and does not reject the law of their God.

They ask me for just decrees;

they want to be near God.

Isaiah 58:5

58:5 Is this really the kind of fasting I want?

Do I want a day when people merely humble themselves,

bowing their heads like a reed

and stretching out on sackcloth and ashes?

Is this really what you call a fast,

a day that is pleasing to the Lord?

Isaiah 58:13

58:13 You must observe the Sabbath

rather than doing anything you please on my holy day.

You must look forward to the Sabbath

and treat the Lord’s holy day with respect.

You must treat it with respect by refraining from your normal activities,

and by refraining from your selfish pursuits and from making business deals.
